After a loooong wait, Pretty Little Liars returned with an extra spooky Halloween episode.

There were so many frightening, action-filled moments that I felt like "This Is a Dark Ride" was even more exciting than this summer's finale. It definitely racheted up the anticipation for the new season. The premise, a Halloween party train, offered many opportunities for masked villains to easily make their way to our titular liars, with deadly consequences.

*Sigh* If only all the episodes could be like this. Oh, well. On to the show because there's lots to cover!

The Halloween episode delivered a little bit of updating on current events in Rosewood. Caleb has recovered from his gunshot wound, though it's still unclear how he got shot. It did sound like maybe he accidentally did it to himself. Garrett is free, but hasn't yet told Spencer everything he knows. He definitely plans on it; Spencer just needs to be alone first. Garrett gets his chance on the Halloween Train, along with every other A-suspect.

So who do we think was responsible for all that mayhem?

Mona was definitely on the train, making us wonder just how easy it is to escape from that mental hospital or who exactly is helping her out. Her paper mache mask/face was extremely creepy, to say the least. Toby accompanied Spencer, but was conspicuously absent during most of the search for Aria. Lucas had an odd moment with a suddenly back in town Jason before both disappeared. Noel and Jenna were there to annoy the liars with their pranks and insults. Paige was also present as Emily's stylish date (good thing for Spencer!).

We know Toby and Mona are part of the A team, but what about the others? Actually of all the suspects, I was most convinced that the one person who wasn't on the train was the guiltiest. Ezra conveniently couldn't make it to the party because of job interview. But he gave a lot of meaningful looks towards Aria and her costume, and then he magically appeared at the end of the episode to comfort his almost-murdered girlfriend. I just don't trust Ezra.

And what do you make of Garrett's confession? He claims that he only let Jenna think that he killed Ali, and when he returned later, he saw Ali talking to Byron. Was he telling the truth? Did A just get him released so he could be killed? I tend to think that anyone who is murdered by A knows the real story behind Ali's death and the weird surveillance of random girls. Poor Garrett just didn't get out of town soon enough.

So, I think maybe Aria's father was somehow involved with Ali, but he was probably only being blackmailed by the little secret-hoarder.

The episode had plenty of scares - from Aria's private time with Garrett's body to Spencer's fight with a cross-dressing masked A - but the biggest creepy moment came at the end when the drink carrier was toppled over revealing that the ice was covering up Ali's body the whole time. GROSS!

The train wasn't the only place with scary events. Ashley encountered a very frightened and very cold little girl at her home; but every time she tried to show the girl to Pastor Ted, she disappeared. The girl said she wanted to call her mom, but her mom just got upset. She also talked about her sister who likes to lie and fight a lot. Was she a ghost? And who's her sister?

Could the show be referencing the twin story from last Halloween episode? Or is this another nod to the "Ali has a twin" theory?

Regardless, the show definitely left us scratching our heads when that hand emerged from the dirt. Was that flashback to the night Ali was murdered?

I guess we'll have to wait until the winter premiere.
